Only #1 has actually been submitted to me but 2, 3, & 4 are all in discussions.

So if it were you, which one of these options would you do? You can pick up to 2 if you would like since I'm not confident which of the last 3 will definitely be agreed to by their owners although all the options have been discussed.

Thanks everyone and rep (once the 24 hours is up) to everyone that responds with their opinions!
